SRAM Static RAM
A random access memory (RAM), faster access speed than DRAM, unlike the DRAM need not stop REFRESH, but higher manufacturing costs, is often used as a cache (CACHE) memory usage.

SRT speech recognition technology
IBM speech recognition technology, immersed in the field of study has been fifty years in the science and technology research and development play a vital role. Speech recognition technology has not only changed the original data input methods, but also provides new ways people use computers.
Joined IBM in science and technology statistics concepts, known as dynamic programming, to distinguish between speech speed and number of words related to programming issues, a substantial increase in recognition rate. The current application of the product, for example, IBM has launched the country with nine different characters Via Voice software to help computers recognize a variety of languages; In addition, the more active areas of expertise vocabulary build libraries, such as law, medicine, etc. to further improve the application-specific recognition rate.

SS7 (Signaling System No.7)
MTP
The first layer of SS7 signaling data link layer (Signalling Data Link Level), also known as Physical Layer (Physical Level), which defines the signal chain of physical, electrical and functional characteristics in order to provide entities to send and receive SS7 signaling links. The second layer is called the signal link layer (Signalling Link Level), which is responsible for ensuring that SS7 signaling messages in the physical layer send and receive reliability. The third layer is called the signal network layer (Signalling Network Level), the main functions of the signal actions and signal network management messages. The above three together as the message transmitted to the Department (Message Transfer Part MTP). Signaling data link with a two-way transmission link (Transmission Link), as well as the transmission link and the second layer of the communication interface to provide signal transmission between the two signals, one-point full-duplex (Full Duplex) channel entities. Transmission link is the same transmission rate and in the opposite direction of the two transmission channels to the composition of the transmission channel can only be used to transmit the signal should not contain other information. The standard transmission rate of 64kbps.
SCCP
SCCP system to assist the exchange of ISUP to do end to end, the main purpose is fourfold:
1. For the ISDN-UP (ISUP) to establish follow-end signal (Signalling Connection).
2. For network management, maintenance centers and among the various switching office (with SP functions are) the establishment of the signal continuation.
3. For future users (User) (such as billing centers) with the switching office (SP points) established between the signal continuation can be sent directly billing information, which no longer need to transport tapes.
4. For the future, the Department of other users (User Part) to establish the use of the signal continuation.
TCAP
Trading capabilities (Transaction Capabilities; TC) also known as Transaction Capabilities Application Part (Transaction Capabilities Application Part; TCAP), in the SS7 network is part of the application layer (Application Layer) in an application service element (Application Service Element; ASE). The aim is to provide the SS7 network, the signal node signal node, follow-related information between the non-circuit transmission, and a variety of applications between them to provide general services. For example, switches and switch between the non-circuit related information exchange successor; switch of the Internet Service Center, a database for number translation (for example, 080 service numbers) enables the services provided by the TCAP to achieve.

SSH Secure Sockets Layer
Ssh (Secure Shell) is to safeguard the safety of a remote computer network connection between the program, which allows users to copy encrypted files between computers, or connect to other computers. Simply put, it is the UNIX r-commands (rsh, rlogin, rcp) encryption version; old BSD r-commands provided by the connection and have not been encoded, it is easy for others to intercept the data intrusion. Implementation of the SSH time, client / server at both ends must be digital certificates and passwords were stored encrypted.
